An almost unbelievable amount of false philosophy has arisen through not realizing what ‘existence’ means…. [It] rests upon the notion that existence is, so to speak, a property that you can attribute to things, and that the things that exist have the property of existence and the things that do not exist do not. That is rubbish . I have dared to puncture several metaphysical balloons and nothing came out of them but hot air.
